Claims priority, application Great Britain March 25, 1954 1 Claim. (Cl. 280-792) This invention relates to means for transporting yarn, and more particularly to a carrier for the transportation of yarn packages wound on tubular supports, e. g. cheeses or cones, from place to place in a textile mill.

A carrier according to the present invention comprises a frame and plurality of movable shelves mounted one above the other in said frame and provided with individual locating means for yarn package supports standing on the shelves. The superposed shelves are spaced as closely as the height of the packages will conveniently permit and at smaller intervals than would be possible with fixed shelves where room is required, additional to that actually occupied by the packages, for the introduction of the packages between the shelves and over the fixed pegs. Easy access for loading and unloading is afforded by the movable character of the shelves; by displacing the upper shelves, the lower ones can be reached for the placing or removing of yarn packages. The carrier thus enables the packages to be more closely spaced, and a greater number of packages can be stored in a carrier of given size. The yarn packages are firmly held and located so that they cannot touch and damage each other.

Preferably, the shelves are made movable by being hinged about their rear edges, and may be disposed in pairs with their hinges running parallel and close together across the centre of the frame, thus forming two sets of shelves back to back on two opposite sides of the carrier. The shelves can then be loaded in order, starting at the bottom (where there may be a fixed shelf) and working upwards, each shelf being swung down over the loaded shelf below it before being loaded itself. Unloading takes place in the reverse order.

The package support locating means are most conveniently in the form of short pegs adapted to engage and fit the lower ends of the package supports, and disposed on the shelf to give the maximum number of packages per shelf. Upper locating pegs or studs may be mounted, preferably resiliently, on the lower face of each shelf except the lowest, to co-operate with the upstanding pegs of the shelf below in locating the package.

The shelves, and the sides of the frame carrying them, may be made of solid (i. e. non-perforated) sheet metal to provide protection for the yarn against handling, oil, dirt and dust. Doors may also be added to the front and back of the frame making the carrier a completely enclosed unit. The carriers may be built so as to stack one above the other for storing purposes, Whether empty or filled with packages. For this purpose the top shelf or shelves can be reinforced and provided with metal brackets at each corner for supporting a further carrier placed thereon.

For moving the carrier from place to place, it may be provided with its own wheels so as to constitute a trolley, or it may be adapted to be fitted on a wheeled base. or carried by overhead rails or otherwise. A carrier mounted on Wheels may be constructed with a packtill 2,819,908 Patented Jan. 14, 1958 age carrying from adapted to rotate relatively to the wheeled base, as described in U. S. appliaction S. No. 495,592, filed Mar. 21, 1955 corresponding to U. K. application No. 8287/54 filed March 22, 1954. Such a carrier allows placing and removal of packages by an operative, on and off any part of the carrier, without changing his position or moving the wheeled base of the carrier.

By way of example, an improved carrier constructed in accordance with the present invention will now be described in greater detail, with reference to the accompanying drawing which is a perspective view of the carrier with a part cut out to show relevant details.

The carrier comprises a metal frame I mounted on a square base 2 provided with wheels. The wheels consist of two castored wheels 3 at two adjacent corners, and two wheels 4 with fixed axes in line with one another at the other corners. The frame is filled in with sheet metal 5 on two opposite sides, and provided with shelves 6 disposed in five pairs one above the other. The lowest pair 7 is fixed and the others are hinged about their adjoining edges. The two shelves of each movable pair are thus disposed with their hinges 8 running parallel and close to another across the centre of the carrier, forming two sets of shelves back to back facing on the two open sides of the frame. Each hinged shelf can be swung upwards from a horizontal position, but is prevented from moving downwards by stop pieces 9 welded on the sheet metal sides 5 of the framework. The shelves 6 lift up to an angle of about 12 to the vertical, Where they are held by ball catches 10 also fixed to the metal sides. Each shelf 6 is provided on its upper surface with two rows of four fixed short pegs 11 over which the lower ends of the bores of the yarn package supports can be fitted. The lower face of the next shelf above is provided with short conical locating studs 12 mounted on rubber rings and located to correspond to the lower pegs, and adapted to enter the upper ends of the bores of the package supports as the shelf is lowered to its horizontal position.

The top shelf 13 is provided with studs face only. Its upper face is adapted for receiving and holding a similar carrier so that two carriers can be stacked one over the other for storing. For this purpose, the top shelf is made of a strong metal reinforced with angle-section steel and provided at each corner of the frame with a low metal wall 14 welded along a short length on each side of the corner so as to receive and locate the wheels of the next unit. A small metal frame 15 is also provided for a label for identifying the yarn stored in the carrier.

The sheet steel sides 5 provide protection for the yarn against handling, oil, dust and dirt, and solid sheet steel shelves also form separate dust proof compartments for the packages. For increased protection, particularly for storing purposes, the carrier is provided with hinged or detachable doors 16 on the back and front.

The carrier is mounted for rotation as at 7 relatively to the wheeled base 2 so that either set of shelves 6 can be reached from one standing position. It is normally locked in one of a plurality of positions from which it can be released by means of a pedal 17. The base is provided with a roller race of large diameter on which the whole weight of the carrier rests. The carrier may be either permanently fixed to the wheeled base 2 or arranged to lift off for stacking while the base is used with another carrier. Metal handles 18 are fixed at each corner of the carrier for steering purposes. To prevent these handles from interfering when the carriers are stacked side by side, the metal sides are shaped with cut-off cor- 12 on the lower -2,s19,9os

ners soithatthe handles do not protrude beyond the square perimeter of the carrier.

A carrier with removable shelves for transporting and storing yarn packages is equally applicable to cop, former, cheese or cone packages, the spacing of shelves and 10- cating pegs being appropriately selected.

Having described our invention, what wew deisre to secure by Letters Patent is:
